TBX Wireless Load Cell Bridge
Turn any standard analog load cell into a wireless load cell with a TBX Wireless Load Cell Bridge. This system replaces the physical cable connection between the load cell and the weight indicator. The TBX Wireless Load Cell Bridge can be retrofitted into old systems or designed for new systems.
